[EpiData-list] appending several files

I have several people entering data to a common structure at different sites. They email me the .rec files which I then combine into one file periodically. It seems as though I need to combine the files 2 at a time. Is it possible to combine them in one step? Are commands available such that a command file could do the task? Another option is to merge the files in SAS after converting the file 2 at a time, but that, too, would take several steps.
